Hearing Aid Design Aspects TRIZ Cases
- Porous Ear Canal Acoustic Element for Occlusion and Noise Balance
Interconnected porous holes balance ear canal pressure and absorb sound, reducing occlusion effects without raising acoustic noise.
- Hearing Instrument Component Placement for 3D Ear Canal Size Prediction
Using 3D ear canal models, this case predicts component placement and size impact before upgrades, reducing uncertainty and analysis time.
- Dual Viscosity Ear Canal Impression Method
Combines low and high viscosity materials to capture medial details and lateral fit for precise digital models.
- Generic Ear Device with Bendable Arm for Bioelectrical Signal Detection
A generic ear device uses a bendable arm to press external electrodes against skin, resolving customization bottlenecks in bioelectrical signal detection.
- Hearing Device Optical Identification Using Segmented Shields
Segmented first and second shields provide flexible optical identification, eliminating costly colored type plate inventory.
- Ear Impression Feature Classification via Shape Context Analysis
Automated ear impression classification uses shape context analysis to label anatomical regions on 3D models without manual intervention.
- Customized Ear Tips With Sealing Structure For Ear Canal Fit
A customized ear tip uses a parameterized sealing structure to match individual ear canal geometry.
